Abstract: Layer structures for RF filters can be fabricated using rare earth oxides and epitaxial aluminum nitride, and methods for growing the layer structures. A layer structure can include an epitaxial crystalline rare earth oxide (REO) layer over a substrate, a first epitaxial electrode layer over the crystalline REO layer, and an epitaxial piezoelectric layer over the first epitaxial electrode layer. The layer structure can further include a second electrode layer over the epitaxial piezoelectric layer. The first electrode layer can include an epitaxial metal. The epitaxial metal can be single-crystal. The first electrode layer can include one or more of a rare earth pnictide, and a rare earth silicide (RESi).

Abstract: Optoelectronic detectors having one or more dilute nitride layers on substrates with lattice parameters matching or nearly matching GaAs are described herein. A semiconductor can include a substrate with a lattice parameter matching or nearly matching GaAs and a first doped III-V layer over the substrate. The semiconductor can also include an absorber layer over the first doped III-V layer, the absorber layer having a bandgap between approximately 0.7 eV and 0.95 eV and a carrier concentration less than approximately 1×1016 cm?3 at room temperature. The semiconductor can also include a second doped III-V layer over the absorber layer.

Abstract: A short annular body for supporting the base of the penis during Jelq and other exercises to strengthen and enlarge this organ. The annular body, formed of a rubbery material, has rounded ends and a beveled portion disposed symmetrically about a central opening. Juxtaposed between the rounded ends, the beveled portion has tapered inner and outer surfaces, which diverge slightly from each other, reaching their greatest divergence midway along the axial length of the annular body. Prior to use, the consumer slides the annular body along the flaccid penis until the beveled portion contacts the crotch. With the annular body so positioned, the base of the penis is supported and ready for exercise. Since the user no longer has to hold its base with his fingers, he can then stroke the penis along its full length without interference from the holding hand, providing for more comfortable and efficient exercise.

Abstract: An adjustable support apparatus including a pole having a plurality of first elements exposed at an exterior surface of the pole. The apparatus also including a clamping member having a top surface, an outer surface and an inner surface having a second element. The second element cooperating with one of the first elements such that said clamping member is at least loosely affixed to the pole. The apparatus further including a collar adapted to be positioned about the clamping element. The clamping member affixing the collar to the pole.

Abstract: An extension arm apparatus is provided for mounting devices such as flat panel monitors above a workspace. The apparatus includes upper and lower channels connected to a pair of endcaps. One endcap may connect to the workspace and the other endcap may connect to an extension arm or the to device to be mounted. At least one of the channels includes a reinforcement structure providing additional support to the apparatus. The reinforcement structure is tapered. A forearm extension may also include a reinforcement structure. The endcaps may have interior spacers that provide clearance for the sidewalls of the channels, which may be fabricated without parting lines.

Abstract: A display arm having an elongated outer housing, an elongated inner housing telescopically engaged within the outer housing, a biasing member coupled with the outer housing and operative to counter-balance the inner housing within the outer housing, and a locking mechanism for locking the position of the inner housing relative to the outer housing. The locking mechanism may include a first locking vane and a second locking vane, each locking vane having a sloped surface abutting an edge of the inner housing and a second surface abutting an interior surface of the outer housing, wherein the sloped surfaces initiate spreading of the locking vanes when the locking vanes are pulled into an extended position by the locking mechanism such that the second surfaces engage the interior surface of the outer housing with sufficient force to prevent movement of the inner housing relative to the outer housing.

Abstract: PURPOSE: To improve the evaporation efficiency of a raw material by mounting an element of a porous sintered metal having the pore size smaller than the size of the solid raw material to a port for introducing a carrier gas into a bubbler vessel.

Abstract: A method and apparatus for the bulk delivery of a precursor, such as an organometallic compound, from a bulk container, such as a bubbler (1) to a plurality of reactor sites (12, 14, 16, 18, 20) wherein a carrier gas (2) is introduced into the container (1) of the precursor to pick up the precursor to form a gaseous mixture. The gaseous mixture is then selectively distributed to one or more of a plurality of reactor sites (12, 14, 16, 18, 20). The gaseous mixture may be stored in a reservoir (9) and be drawn by means of a pressure differential or under vacuum to each of the reactor sites, when required.

Abstract: A seismic expansion joint cover includes a floor bridge panel having mutually perpendicular elongated U-shaped bearing receiver guideways adjacent its opposite ends slidably supported by linear bearings affixed to the floor portions on opposite sides of the gap. The receiver guideways are open vertically to allow the floor bridge cover to displace vertically. A cover plate frame defines the boundaries of a floor recess that receives portions of the floor bridge panel in all relative positions of the floor portions as the width of the gap changes. The portion of the floor bridge panel that overlies the gap is covered by a first floor cover plate, and the recess and the remaining portion of the floor bridge plate are covered by a second floor cover plate, which is supported by the cover plate frame and by the portion of the floor bridge panel that it overlies. The second cover plate is resiliently attached to the cover plate frame so that it can lift up and ride over the first cover plate when the gap narrows.

Abstract: A foot mat comprises a multiplicity of elongated rail members formed by coextrusion of a substantially rigid polymeric material and a compressible polymeric material. Each rail member has a rigid tread-supporting web portion, at least two rigid leg portions, which are adapted to support the tread-supporting web portion stably on a surface, a cushion portion of the compressible material on the bottom of each leg portion, and a pair of rigid bulbous coupling portions of the substantially rigid material, one on each side of the tread-supporting web portion. Each coupling portion is substantially longitudinally coextensive with the tread-supporting web portion and extends generally laterally outwardly from the tread-supporting web portion. A tread member is received on the top of the tread-supporting web portion of the rail member.
